Parent entity looks like this: @Entity @Inheritance(strategy = InheritanceType.JOINED) public class A<E extends AJsonContent> extends AbstractDomainJsonEntity<E, String> { @Id @GeneratedValue(generator = "uuid2") @GenericGenerator(name = "uuid2", strategy = "org.hibernate.id.UUIDGenerator") @NotNull(groups = OnUpdate.class) @Null(groups = OnCreate.class) @Column(name = "a_id", columnDefinition = "VARCHAR(255)") @JsonProperty("aId") @Schema(description = "This attribute indicates unique id of OriginationJsonApplication") private String id; private String aAttribute; } The first child is: @Entity public class B extends A<BAttribute> { private String bAttribute; } The second child is: @Entity public class C extends A<CAttribute> { private String cAttribute; } Here parent has a column of jsonb type whose type is being passed by child entities using generics argument A<E extends AJsonContent> and argument should of subtype AJsonContent. BAttribute and CAttribute are children of AJsonContent and they represent jsonb column. Now, when bRepository.findById() is called, it returns an instance of B with jsonb column CAttribute instead of BAttribute. When I removed C entity completely, then it is working fine. But when it B and C are both together it fetches the wrong jsonb column for the B entity. What could be the reason for this behavior?
